    Abstract: The present disclosure provides a low-molecular-weight Tremella aurantialba glucuronoxylomannan (LTAG) as well as a preparation method and an application thereof, and specifically relates to the technical field of medicine. The LTAG provided in the present disclosure has a weight-average molecular weight of 8,000-24,000 Da. In the method of preparing LTAG as provided in the present disclosure, Tremella aurantialba glucuronoxylomannan is depolymerized by peroxides so as to get low-molecular-weight products, which are then exchanged into pharmaceutically acceptable salts through cation exchange resins. The resulting LTAG has a clear structure, a low viscosity and a good solubility, has a strong immune-enhancing activity, and is capable of acting on TLR4 receptor-activated macrophagocytes and promoting the production of various immune factors, so it can be used in the prevention and/or treatment of immunodeficiency-related diseases.

  • Patent number: 11185796
    Abstract: The present disclosure provides a fast and high-capacity intelligent cellulose-based oil-absorbing material and a preparation method and use thereof. The material includes an intelligent response layer and an adsorption layer. The intelligent response layer is a pH-responsive nanofiber layer with an adjustable pH response performance and is obtained by grafting hyperbranched polycarboxylic acid-modified polyethyleneimine on to carboxylated cellulose nanofibers. The hyperbranched polycarboxylic acid is prepared by melting and polycondensing at a high temperature, using trimethylolpropane as a core, citric acid as a reactive monomer, and p-toluenesulfonic acid as a catalyst. The adsorption layer is prepared by coating ferroferric oxide with the carboxylated cellulose nanofibers to prepare magnetic carboxylated cellulose nanofibers, and then modifying the magnetic carboxylated cellulose nanofibers with hexadecylamine.

  • Patent number: 10981816
    Abstract: The present invention belongs to the technical field of wastewater treatment, and particularly relates to a method for pre-conditioning high-calcium wastewater by calcification blocking, and a device for implementing the method. The method for treating high-calcium wastewater by calcification blocking includes mixing high-calcium wastewater, an alkalizing agent and a chelating agent, and carrying out alkalizing conditioning pretreatment under a condition of stirring by bubbling of a biogas, so as to obtain pre-conditioned wastewater. The pre-conditioned wastewater is mixed with anaerobic granular sludge, and an anaerobic reaction is performed in a high hydraulic shear flow field formed by the biogas, so as to generate the biogas and calcium scale. A part of the biogas for the stirring is refluxed by bubbling of the biogas and the rest of the biogas is refluxed for forming the high hydraulic shear flow field.

  • Publication number: 20200388013
    Abstract: An inverse matrix iterative deconvolution method for spectral resolution enhancement comprises the following steps: step 1, sequence convolution and convolution square matrices; step 2, cumulative multiplication of convolution square matrices and convolution kernel function peak broadening; and step 3, peak resolution enhancement. The invention achieves the purpose of narrowing the peak width by multiplying primitive functions by deconvolution matrices. Further, the invention provides a method for constructing a deconvolution identity matrix to achieve the deconvolution effect with an expected precision. The calculation process is fast and controllable with stable and accurate results, and the application range is wide. The method can be used for resolution enhancement of molecular spectra such as Raman and infrared spectra, as well as other spectra with symmetrical peak patterns such as mass spectra, nuclear magnetic resonance, XRD and XRF.

  • Publication number: 20140090411
    Abstract: A heat pump system, including a main heat pump system and a directly expanded strong cool-heat radiation plate provided on the building surface and serving as the terminal of the main heat pump system. The directly expanded strong cool-heat radiation plate enables refrigerant in the main heat pump system to circulate therein. Since the heat pump system of the present application adopts the directly expanded strong cool-heat radiation plate as the terminal of the main heat pump system, refrigerant in the main heat pump system may exchange heat with air by means of the directly expanded strong cool-heat radiation plate directly, instead of secondary heat exchange of the refrigerant loop and the water circulation loop, thereby reducing loss in intermediate heat exchange, improving the heat exchange efficiency and heat utilization, and omitting the circulating pump for water circulation. An air-conditioner with the heat pump system is further disclosed.
